慢性前列腺炎患者健康教育需求调查分析

目的了解慢性前列腺炎患者健康教育需求，并提出行之有效的健康教育方法和内容。方法对102例慢性前列腺炎患者采用问卷式调查方法进行调查。结果患者对用药指导、生活、饮食习惯内容需求强烈；与医护人员交谈、为病人提供科普手册这两种方式最受欢迎。结论护士在开展健康教育时，应根据病人健康需求提供个性化健康教育。以促进患者身心康复，提高其生活质量，同时增强了护士健康教育能力。     

The diagnostic value of image guided percutaneous fine needle aspiration biopsy in equivocal mediastinal masses

Background and aims The aim of this study was to assess the diagnostic value of image guided percutaneous fine needle aspiration (FNA) biopsy in equivocal mediastinal masses.Patients Sixty-six patients with an equivocal mediastinal mass who underwent FNA biopsy between 1993 and 2003 were eligible for final analysis. The cytological and definitive diagnosis of masses were grouped as primary 22 (33%)−30 (46%) and secondary (metastatic) neoplasms 18 (27%)−18 (27%) and nonneoplastic lesions 20 (30%)−18 (%27) respectively.Results The diagnostic accuracy (%95 C.I.) of FNA biopsy for primary mediastinal neoplasms, secondary neoplasms and nonneoplastic lesions were found to be 93.3 (83.8–98.2)%, 100 (95.1–100)%, 93.3 (83.8–98.2)%, respectively.Conclusion Image guided percutaneous FNA biopsy is a safe and highly accurate diagnostic method for equivocal mediastinal masses.     

Magnesium intake is inversely associated with the prevalence of tooth loss in Japanese pregnant women: the Osaka Maternal and Child Health Study.

There have only been a few studies on the role of mineral intake in tooth loss. We investigated the association between mineral intake and the prevalence of tooth loss in Japan. We used the baseline data on 1002 pregnant women who were enrolled in the Osaka Maternal and Child Health Study between November 2001 and March 2003. Tooth loss was defined as the previous extraction of one or more teeth. Nutrient intake was assessed by a validated diet history questionnaire. Prevalence odds ratios and confidence intervals were estimated by applying a multiple logistic regression model. The adjusted odds ratio upon comparison of the highest quartile with the lowest quartile of magnesium intake was 0.64 (95% confidence interval, 0.42-0.99), showing a tendency for an inverse dose-response relationship (p for linear trend = 0.05). There were no associations between the level of consumption of calcium, phosphate, iron, zinc, or copper and tooth loss. The present findings suggest that intake of magnesium is related to reduced prevalence of tooth loss among young Japanese women.     

Liver and lung resection for colorectal metastasis

Aim: To examine the survival benefit of liver and lung resection for colorectal metastasis and the potential prognostic factors that affect patient survival. Methods: All patients who had resection of lung or liver metastasis for colorectal metastasis in Queen Elizabeth Hospital, Hong Kong from 1995 to 2004 were retrospectively reviewed. The overall and disease‐free survival was analysed, in particularly between liver and lung metastasis. All factors that may have affected the survival were entered into Cox's proportional hazards regression model to identify significant variables associated with survival. Results: At 5 years, the overall survival of patients who had resection of lung and liver metastasis was 44% and 38%, respectively; the disease‐free survival was 26% and 24%, respectively. Overall and disease‐free survival of patients with resection of lung metastasis was comparable to those with resection of liver metastasis. The differentiations of primary tumour and time to metastasis were shown to be significant prognostic factors influencing overall survival. Those patients with systemic chemotherapy after resection of colorectal metastasis demonstrated a significantly higher probability of overall survival. Conclusion: Resection of lung and liver metastases from colorectal origin was safe and both procedures improved survival. The use of chemotherapy after resection of metastasis significantly improved the overall survival.     

电视胸腔镜辅助胸腺切除术

目的探讨电视胸腔镜辅助胸腺切除的临床应用价值. 方法 2002年9月～2004年6月,18例胸腺疾病和重症肌无力(myasthenia gravis,MG)行胸腔镜辅助下胸腺切除手术,其中胸腺全切7例,11例MG行胸腺扩大切除. 结果 17例在胸腔镜辅助下完成, 1例中转小切口(7 cm)开胸手术.3例MG术后须短暂呼吸机辅助通气(<12 h),二次气管插管1例,余无严重并发症,无手术死亡.手术时间47～115 min,平均95 min;胸腔引流时间1.2～2.6 d,平均2 d;术后住院时间4～9 d,平均5.5 d.9例良性胸腺瘤或胸腺囊肿随访3～20个月,平均13个月,无复发.11例MG随访3～19个月,平均10个月,4例症状完全缓解,7例都分缓解. 结论胸腔镜辅助下胸腺切除手术,具有创伤小、恢复快等优点,胸腔镜下胸腺扩大切除治疗重症肌无力在技术上是可行的.
